Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Preheat the oven to 400°F (200°C).
In a bowl, beat together the sugar, butter, and lard until very light.
Add the eggs without beating them.
Mix in the baking powder and lemon juice.
Gradually add flour until the dough is thin enough to roll out.
Shape and bake
Roll the dough thinly, using as little flour as possible.
Cut into shapes and place on a baking sheet.
Bake until lightly golden.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and flavor while creaming with sugar to trap air for a light texture.
- Lard
- Adds tenderness and shortness, giving the cookies a crumbly bite.
- Sugar
- Sweetens the cookies and helps them brown lightly in the oven.
- Eggs
- Bind the dough and add structure and richness.
- Baking powder
- Releases gas in the oven, helping the cookies rise and turn lighter.
- Lemon juice
- Adds acidity and bright lemon flavor that balances the sweetness.
The step that matters
Add the eggs without beating them. Beating eggs into the creamed fat and sugar can add excess air and toughen the dough once flour is added. Gentle mixing keeps the texture tender and the cookies from spreading or puffing unevenly.

Fit is the average pairing score against butter, sugar, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
